A box was opened, Lu Xiaoyou counted the thirty thunder cannons inside, and then closed the box again with a "snap".

"Let's go. I'm not in Hanzhong. You have to train our soldiers well."

"Where are you going?" Li Zeyi walked beside Lu Xiaoyou carrying a bundle of arrows and said, "The autumn harvest is coming soon. What business can we do while the military camp is harvesting grain?"

"The Public Opinion Department is short of manpower and will be seconded for a while."

"When you become disabled, do you plan to settle down in the Department of Public Opinion?"

Li Zeyi has always been so unpleasant to talk to and has no friends.

Lu Xiaoyou didn't care about this, and said seriously: "Don't ask so many questions, I'm leaving."

He held the box in one hand, took the bundle of arrows in the other, and turned towards the Hanzhong city gate.

Li Zeyi casually took out a message from his arms and stuffed it into Lu Xiaoyou's mouth.

"You don't have free hands, so bite on, otherwise you won't be able to enter the city gate with your weapons."

After saying that, he got on his horse, took away Lu Xiaoyou's horse, and ran back to the military camp.

"Woo...Woo!"

Lu Xiaoyou put down the box in his hand, took the letter and stuffed it back into his arms.

"I can put my things down, why can't I get in?"

After entering the city, we turned around the Han Dynasty General Worship Platform in the south of the city, passed through an inconspicuous alley, and entered the courtyard of the Public Opinion Department. Our eyes suddenly opened up.

More than thirty people were preparing their luggage in the courtyard.

Different from the military, and different from the Military Intelligence Department, these people come from all kinds of people, and there are even a few women who are disabled and have a strong sense of publicity.

Lu Xiaoyou stood still in front of the crowd.

After a while, I saw Li Xia striding past with a few people.

"Lu Xiaoyou, come with me."

"Here!"

~~

Yan Rong covered his face with a veil, followed Li Xia, sat down in the hall, and listened to Li Xia's orders.

"I have something that needs to be handled in Lin'an at the moment. The Public Opinion Department is short of manpower. Xiaoyou, please come and take care of the thirty-three new people outside."

"Here!"

"Don't be so loud. This is different from the battlefield. Let's talk about the purpose first. Princess Rui is dead. I suspect someone has tampered with it. Go and investigate and find out the murderer."

"General...I understand."

"Let's talk about the plan. I wrote a letter to Jia Sidao. When you arrive in Lin'an, go to the shop and steal his reply and read it. After reading it, leave a mark. I will know when I receive the letter. If Jia Sidao

The letter says that he has sought justice, so you can come back. If not, check, first, the medicine, and second, whether Jia Sidao destroyed any evidence."

"I see."

"We don't have many hidden connections in Lin'an." Li Xia cited someone in the hall and said: "This is Mr. Lu Shu. He has some connections in Lin'an. He will take the lead in investigating the murder. You will lead the team and kill people."

"Well, I've seen Mr. Lu Shu."

"Don't worry, Prince. It's a small matter."

Li Xia said: "This is Wang Cui, the bodyguard of Princess Rui, who will also contribute. I have arranged a ship to go directly to Lin'an to sell goods. There are ordinary business travelers on board, so don't get involved with them."

"..."

Yan Rong silently watched Li Xia's arrangements, sniffed slightly, and another tear fell on her hand.

Afterwards, she followed Li Xia out of the door and looked up at the sky in the southeast, with cruelty in her eyes.

"I have killed many people in my life, but few people come to seek justice from me."

Li Xia said something, pointed at Wang Cui who was walking in the crowd, and said: "Hundreds of people from the Wang family in Longxi died in my hands. The Wang family still dare not come to me for revenge. There are many people who assassinated me, but only this one."

Wang Cui came to seek justice at the request of Zhao Jin."

"She just wanted to avenge her father, and she didn't really take action..."

"I mean, if Zhao Jin wants this justice, then give it to her." Li Xia said: "I killed Zhao Yun because he deserved to be killed. If that little woman can't look at the world, then just look at Lin'an. Her innocent and tragic death is enough.

Seeing that she, Mrs. Zhao, is not qualified to come to me to seek justice."

Yan Rong looked up at Li Xia, was stunned, took his hand, and said softly: "Just say you are doing it for me, I don't care about justice."

"You care about my justice, and I care about you."

"Humph, you're training others again, and you still want to know how virtuous the demon concubine can be?"

~~

This matter was just a trivial matter to Li Xia, so he arranged for Yan Rong to return to Baoyuan first, and then he rode his horse to the military camp outside the city to inspect the harvest.

He almost never slumps down. Although he does everything calmly and leisurely, he does a lot in one day.

Let's just say that today, Li Xia got up early and took his family to exercise together. After that, he met with Zhang Hongdao and arranged for people to go to Lin'an to inspect the military settlements. He went outside the city to plan the new city of Hanzhong, arranged for officials to go to various places in Sichuan and Shu to supervise grain taxes, and approved the shogunate's plan.

Documents...

Before dinner, he went to the Statistics Department to meet with Li Ye.

…

"I was just about to ask for an audience with the county king, but unexpectedly he came in person."

Li Ye was sitting there talking to his subordinates. He turned around and saw Li Xia walking into the hall. He was still satisfied with Li Xia.

Frugal, capable, never shouting at each other when going out, and full of energy.

In his early years, he also met several officials of the Song Dynasty. The small envoys also sat in the hall with airs and arrogance all day long, shouting and talking about doing things, giving orders, and they were extremely impressive.

, has become a trend.

Just like that, it would be strange to be able to recover it.

It's really strange, how could such a Song Dynasty produce such a powerful and vigorous person as Li Xia?

What's even more rare is that what goes up and what follows leads to results, and the official style of Sichuan and Shaanxi is also so frugal and capable.

"If someone asks someone to invite Mr. Jingzhai to come over, and it takes only a round trip to pick up some files, why don't I just come over and finish the matter."

Li Xia knew that Li Ye liked to hear this, and sure enough, as soon as he started talking, the old man was already stroking his beard and jaw.

"This is a new batch of coupons. Please take a look at them. Do you think they are easy to forge?"

Li Xia reached out and took it. First it was paper, but the craftsmanship was different from before... As for the digital code, he actually couldn't understand it.

"I don't know how far that opponent's arithmetic talent is. I recently learned that the academic talent of the Song Dynasty actually published a wonderful book on arithmetic called "Nine Chapters of the Book of Numbers" more than ten years ago. It's amazing."

Li Ye didn't wait for Li Xia to put down the coupon in his hand, but handed over another book.

Li Xia knew at a glance that it was printed by Shicai Tang.

I have to say that Jia Sidao and Liao Yingzhong did their best in printing books.

Li Ye had already come up, pointed, and said: "Let's look at the 'Dayan Qi Yi Technique' and the 'Positive and Negative Square Root Technique'. They are purely based on algebraic addition, can be unified to operate, and can be extended to any equation..."

Li Xia really couldn't understand. First of all, his mathematics was very poor and he had almost forgotten the equations. Secondly, many of the terms in Li Ye's mouth were different from what he knew.

What are "Shangchang", "Shichang" and "Derived Numbers"? When I glanced at the "Nine Chapters of the Book of Numbers", I saw only one line: "It is said that every number has a numerator. I have been asking for a long time..."

I knew every word, but I had no idea what it meant.

Li Xia just kept a polite smile and listened to Li Ye talking endlessly.

"Did Mr. Jingzhai say that he can solve any higher-order equation?"

"That's what it means."

Li Ye inexplicably decided that Li Xia was an arithmetic genius and liked talking to him about these things. He talked for a long time.

"What I mean is that when we talk about mathematics, we should use simpler words and be more straightforward when compiling books, so that we can spread arithmetic more easily. For example, we can put this long paragraph of text into a formula like this

...What does Mr. Jingzhai think?"

"It's quite concise and easy to understand." Li Ye twisted his beard and pondered for a while, then asked: "Replacing it with this symbol is to make it difficult for people in the Song Dynasty to understand?"

"You can also say this. The formula is listed in this way, and it is convenient for shops in various places to check."

Li Ye felt that if he wrote some introductory books and used some weird symbols as Li Xia said, it would really lose the style of a famous scholar, and he was reluctant to do so.

But thinking that he needed to carry forward what he had learned in his life, and that it was necessary for official duties, he still nodded in agreement.

"That's good." Li Xia was finally able to ask about the business he cared about, "Is the impact of counterfeit currency serious?"

"It makes some money, but it doesn't matter." Li Ye shook his head and said: "The first batch of coupons is not large, far from what is needed in Sichuan and Shaanxi. When I was planning, I had already considered the possibility of counterfeit currency.

In this situation, including the second batch of coupons, even if there are counterfeit coins, I have already calculated that it will not have any impact on prices..."

"But they will make money from our supplies, won't they?"

Li Ye glanced at Li Xia and felt that the prince was really stingy. He had a territory thousands of miles away, so he still cared about that little thing?
